To all whom 'it may concern:

Be it knownthat I, WALTER YossLEn, a citizen of the United States, residin in the city of Richmond, in the county of ayne,

and in the State of Indiana, have invented certain new and useful Im rovements in Lawn-Sprinklers, of which t e'followin is afull, clear, and comprehensive speci cation. y

My present inventionrelates to an automatic rotary lawn sprinkler, in which the operation is actuated by the water as it seeks the exit.

My object in this invention, broadly Speaking, is to provide a lawn-sprinkler which is neat and attractive in appearance,

strong and durable in construction, highlyeicient and practical in operation, and whichl after being connected to the water supply will be entirely automatic in operation.

A further object is to provide A a lawn' s rinkl'er having a relatively stationary vertical stem, .a pair of oppositely disposed horizontal arms rigidly connected together,--

with means whereby the arms mayrevolve horizontally, aswivel union for vconnecting the revolving portions to the stem, La base supporting said parts, and having means wherebythe whole may be easily .moved Irom place to place over a lawn.v.AI 1d,

" finally, my object 'is to .provide aflawn sprinkler of simple and lnexpensive con` struction and which can be manufactured Other objects and particularadvantages of my invention will suggest themselves in the course of the following description.

Formed vertically through each of Asaid feet is a boltaperture, as shownin Fig. 1, which are forjtlie purpose hereinafter set forth.

In the center of the base A is formed a comparatively large aperture,.through which may freel pass the lower portion of the ipe B. 'libe lower portion of said pipe B 1s .threaded on its periphery and a nut A'Gis run on said Zthreaded portion, after which the lower; end. of; the :pi .e .Bl is inserted he base, with said nut restinon' top of the base,;a s shown.

The'metaber'-2 ...1s. v head- `Whi ch* s 1 adapte d.lto" be.seated f inL'membei'. 1 andLthereretained-in.revoluble position 4by .theband 3.v The .periphery of the member 1 .is threaded to' coact with the interior threads of thebandS, there being a flange formed around the lower portion of member '1 with which thelower edge of. the 1.10 j l of t e-'pipev B, ater'which the vnut Clisi-'un V u with the bevel of member 1. It 1s to be un-` dei-stood that a central aperture is formed through the union to allow a flow of Water therethrough from the pipe B, and the construction of the union 1s such that the upper melnber of the union may revolve while at the same timea water tight connection is formed between the members of the union.

'lhreaded in the'upper end of member 2, and extending upward in alinement with pipe B, is the pipe I. Threaded on the upper end of pipe I is the T-tting J. n

Extending out in opposite directions from the fitting J are the two pipe arms K and L, which have their outer ends closed by the respective caps M and N. It should be understood that the arms K and L have interior connection through the fitting J, the pipe I, the union, and the pipe B, to the water supply. 4 f

Openings and are formed through the arm K, and like openings y and y are formed through the arm L, which openings are directed upward, and they are located near the fitting J, as shown in Fig. 1. And openings z, e, e and e are formed in one side of the arm K, which openings are not in line with each other but are locatedspirally as shown. Also openings fv. v. 'v and 'v are formed in one side of the arm L, which openings are not in line with each other but are located spirally as shown. yAs viewed in Fig. l the openings e are on the opposite side from the openings c, that is they are directed oppositely thereto. Said openin s in the arms K and L are graduated, that 1s they lare of Varying dimensions, in order that the water may pass through all with substantially equal force, or otherwise as desired.

Disposed through the member 1 of the union is an oil duct a which leads from the exterior and opens into the bevel face of the member l, as shown in Fig. 2. A force-feed oiler 4 is screwed in and extends out from s-aid duct, whereby oil may be forced into the bevel contactfaces of the members 1 and 2.

Should it be desired to place the sprinkler on runners, then I have only to attach the runners 5 and (3 by bolts to the feet of the base A, as shown in Fig. 5, and a chain or rope 7 may be attached thereto and extend out some distance in order that the sprinkler may be moved over the lawn without the operator coming within the radius of the sprinkler. Or, in place of said runners, I may secure the axles 8 and 9 to the. feet of the base A, as shown in Fig. 6, mounting the wheels v10 on the axles, and then attaching the rope or chain l1 to one of the axles for the purpose of moving the sprinkler over the i 'under pressure will cause the arms K and L to revolve at a. speed depending on the pressure. As the wat-er is discharged vfrom said apertures it descends to the ground in drops simulating rain, and the water is evenly distributed over a comparatively large extent of surface.

Having now fully shown and described my invention, what I claim and desire to secure yby Letters Patent of the United States, is-

A lawn sprinkler substantially as set forth, comprisin a base; a vertical pipe secured to and exteni connecting a flexible water supply pipe to the lower end of said pipe; a union attached to the upper end of said pipe,-said union comprising a female member having a beveled concave face, a male member having a beveled head adapted to fit said face in the female member, a band connecting the female and the male member to form a water-tight joint but allowing the male and the female members to revolve independent of each other; a force-feed yoiler extending into said band to supply oil to the contacting faces of said male and female members; a second pipe extending up from said union; pipe arms extending out at right angles from the upper end ofthe last named pipe, said arms each being provided with a plurality of escape apertures formed therein 'to allow water to escape therefrom both outwardly and upwardly at right anglesl therefrom; runners removably mounted to the base; means whereby wheels may be employed in place of said runners; and means whereby the device may be operated over the lawn by a person located at a distance from the device, all substantially as shown and described.

In testimony whereof I have hereunto subscribed my name to this specification in the presence of two subscribing witnesses.
